R&D Report 1973-16 : Medium frequency directional aerials L.K. Bradley The principal design considerations for highly directional MF aerial arrays are presented together with a detailed calculation relating to a particular example of an in-line four-element directional array. Techniques for providing phase control and power splitting are also considered.

R&D Report 1975-28 : The subjective effects of interchannel phase-shifts on the stereophonic image localistion of narrowband audio signals. J.S. Bower A previous report studied the effects of interchannel phase-differences on stereophonic-image localisation. The present report continues this work by quantifying some of the frequency-dependent localisation effects which occur when phase-shifts are present...

This resource contains demonstrations used to illustrate the theory and applications of lasers and optics. Lasers today are being used in an ever-increasing number of applications. In fact, there is hardly a field that has not been touched by the laser. Lasers are playing key roles in the home, office, hospital, factory, outdoors, and theater, as well as in the laboratory.
